Migration Steps from Version 3.3.x to 3.4.4

Pulse Upgrade Steps (Core Services Server / Addon Services Server)

Update Configuration:
- Update the ImageTag in the $AcceloHome/config/accelo.yml file to 3.4.4.
Push Updated Configuration to Database:
- Run the following command:

Bash
    
xxxxxxxxxx
 
accelo admin database push-config
Copy

Download Necessary Images:
- Ensure you have downloaded or loaded all the necessary Docker images for version 3.4.4.
Update Accelo Binary:
- Download the new Accelo binary.
- Replace the older Accelo binary with the new one.
Run Migration Command:

Make sure you run the command from $AcceloHome.
Do not change the value of -v from 3.4.0 unless explicitly advised by Engineering. The following command needs to run on all Pulse nodes including standalone nodes i.e. nodes where PULSE_SA_NODE is true. Examples of such nodes include but aren’t limited to Logsearch, FS Analytics V2, Dashplot .

-i : This indicates the version you are migrating from. For example, to migrate from 3.3.8 to 3.4.0, run:

Bash
    
xxxxxxxxxx
 
accelo migrate -v 3.4.0 -i 3.3.8 -b
Copy

For Multi-Cluster:

Bash
    
xxxxxxxxxx
 
accelo migrate -v 3.4.0 -i 3.3.8 -a -b
Copy

Handle Migration Issues:
- If any issues occur during migration, rerun the same command.
Restart Containers:
- Restart all containers to use the updated images:

Bash
    
xxxxxxxxxx
 
accelo restart all -d
Copy

Uninstall Hydra Agent:
- Run the following command:

Bash
    
xxxxxxxxxx
 
accelo uninstall remote
Copy

Install Hydra Agent:
- Run the following command:

Bash
    
xxxxxxxxxx
 
accelo deploy hydra
Copy

If Logsearch is deployed in standalone mode:
- Check if yarn_app_es_urls is present in override.yml
- If the above is present, change the port number from 19013 to 19051.

Bash
    
xxxxxxxxxx
 
yarn_app_es_urls: <http://<LOG_SEARCH_HOSTNAME>>:19051
Copy

Reconfigure Cluster:
- To get the updated configuration for agents, run:

Bash
    
xxxxxxxxxx
 
accelo reconfig cluster -a
Copy

Push Updated Configuration to Database:
- Run the following command:

Bash
    
xxxxxxxxxx
 
accelo admin database push-config -a
Copy

Configure MongoDB Cleanup & Compaction:
- To configure when Gauntlet Snap will run MongoDB cleanup and compaction, run:

Bash
